CHURN.

SPECIFICATION forming part of Letters Patent No.. 296,202, dated April1, 1884.

Application filed February 18, 185:2. Renewed February 5, 1834. (Nomodel.)

To all whom it 12ml; concern.-

Be it known that 1, Mac N. MCKINNEY, of Jackson, in the county of Hindsand State of 1 Mississippi, have invented certain new and usefulImprovements in Chorus; and I do hereby declare that the following is afull, clear, and exact description of the invention,

which will enable others skilled in the art to which it appcrtains tomake and use the same,

reference being had to the accompanying drawings, which form a part ofthis specification, and in which Figure 1 is a side elevation of myimproved churn power and dashcr. Fig. 2 is a perspective view of aportion of the top part of the frame, one of its side pieces having beenremoved to show the double crank and its belts.

Fig. 3 is a sectional view through the double crank and the buckledendof one of the belts attached to it. Fig. 4; is a transverse verticalsection through the pulley-box, pulley, and coupling-sleeve; and Fig. 5is a perspective view of the lower part of the dasher-staff and composedof two parallel side pieces, G 0,

connected at their outer end by parallel crosspieces D D, said frame, itwill be seen, forming an arm of suitable length extending from the topof post B parallel to the platform or bed-piece A. In each of the sidepieces 0 is a box or hearing, D, for the ends of the double crank E E.These boxes slide in slotted ways 0 c in the sides 0, in which they maybe properly adjusted by binding-screws d d to regulate their distancefrom the outer end of the arm or frame. The sliding bones having beenproperly adjusted in their ways to take up slack of the belts, they arefixed in their places by screwing up the binding-screws d (1 until theirheads press or bind against the sides of the ways 0 c across the slotformed by I said ways; as shown in Fig. l of the drawings-that is tosay; the ways 0 being slightly dovetailed in cross-section, and thesliding boxes I) being similarly dovetailed, the tightening of thescrews ('6 (1, so as to bring their heads transversely across the ways,will operate to wedge the boxes firmly in their ways. lhe double crank EE has a crank and handle, E, for rotating it.

F and F are belts or hands, of leather or other suitable material, whichare buckled at f and f, respectively, around metallic sleeves or collarsc e, placed upon the cranks to prevent wearing of the belts. By shiftingthe position of the buckles f and f the bands may be tightened to takeup slack when required, which may also be effected by moving the boxes Din their slotted ways c.

The dasher-staff (shown at G) is inserted into a sleeve or thimble, II,at the lower end of the pulley-shaft I, and held therein removably bythe set-screw i. p

K is the pulley or drum, which is j ournaled between the parallel endpieces, D D, as shown in Fig. 4., and has secured to it the ends of thebelts F and F, which are wound around it in opposite directions. Byturning crank E a rotary reciprocating motion is imparted to the pulleyK and dasher-staff G by nieansof the belts F and F, and this without thejerky motion which results from the employment of the usual crank -and-pitman mechanism. The lower part of the dasherhas a cross-head, h, atits lower end, from which two arms, A", project upward on opposite sidesof the staff, parallel to each other. These arms increase in widthtoward the top, where they are out off slantingly, as shown at 7; and(see Fig. 5,) the slants or inclines being in opposite directions. Itwill also be seen that the cross-head I is beveled on both sides of thecentral tapering staff, G, as shown at the rounded parts h audit,forming a sharp ridge on each side. By this construction of the dasherand its staff a downward draft will be created in the center of thechurn and an upward draft or current along its sides, caused by thebeveled side wings or arms, k k and k is, thus causing a thoroughagitation of the cream and commingling of the butter globules. Thisshape of the dasher also admits of the staff G is cut off tapering, asshown at g, and

ready removal of the butter when inade,without the necessity of removingthe dasher from the churn.

I am aware that it is not new to operate a churn dasher by means ofbelts or bands wound around apulley at the head of the staff or aroundthe staff itself, nor do I lay any claim to this construction andarrangement,

broadly; but,

Having thus described my improvement, I claim and desire to secure byLetters Patent of the United States 'Ihe dasher composed of the staff G,cut away or tapered on opposite sides, g, at its Witnesses:
